Final Flight of SpaceX CRS contract
The spacecraft launched on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida and arrived a the International Space Station on Monday, March 9.
Dragon will joined three other spacecraft currently berthed at the station. The robotic installation of Dragon was to the Earth-facing port of the Harmony module. Dragon is scheduled to remain at the space station until April 9, when the spacecraft will return to Earth with research and cargo. Currently Dragon is only one of two craft that are certified to deliver cargo and return to Earth. Other Craft are going through the certification process currently.
This delivery, SpaceX’s 20th cargo flight to the space station under NASA’s Commercial Resupply Services contract, will support dozens of new and existing investigations. NASA’s research and development work aboard the space station contributes to the agency’s deep space exploration plans, including future Moon and Mars missions.
This will also be the last SpaceX CRS mission to utilize a Dragon 1 vehicle. All future missions under the CRS-2 contract will utilize the upgraded Dragon 2 spacecraft and will return to Earth with a water landing in the Atlantic Ocean.

During SpaceX’s 20th Commercial Resupply Services Mission to the International Space Station, the Dragon cargo spacecraft will deliver about 4,500 pounds of supplies, equipment and numerous science investigations to the crew aboard the station.
- Bartolomeo is a new European Space Agency commercial research platform to be installed on the exterior of the orbiting laboratory.
- The “Gut-on-Chip” experiment seeks to provide a better understanding of how microgravity & other potential space life stress factors impact intestine immune cells. A focus of the experiment will be on susceptibility to infection, which could help develop technology to protect astronaut health on future long-duration missions.
- Advanced Combustion via Microgravity Experiments (ACME) is not about the Road Runner. Rather it is a project of six independent studies focused on gaseous flames that will be conducted in the Combustion Integrated Rack onboard the orbiting laboratory. Fire acts differently in space and needs to be studied further to improve protective systems.
- Aboard the space station, NASA will use the Japan Aerospace Exploration Agency’s Electrostatic Levitation Furnace (ELF) for two new experiments. 1st , Thermophysical Property Measurement investigation looks at small spheres of metal to provide a better understanding of how to measure liquid metal properties; 2nd, the Origin of Fragility in High-Temperature Oxide Liquids experiment looks into high temperatures applied to those same small spheres of various metal oxides.
- The Advanced Colloids Experiment Temperature-2 (ACE-T-2) experiment will look at the complex structures of micron-scale colloidal particles, and how they assemble in microgravity environment. Scientists will observe these particle interactions when different temperatures are applied to them with an electron microscope.
- Biological Research in Canisters-Light Emitting Diode-002 (BRIC-LED)-002 test if spaceflight affects the ability of plants to defend themselves against pathogens. Should travel to Mars bring plants for food production, this research will provide a better understanding of how plants function in microgravity and also help develop better techniques for Earth.
- VEG-PONDS-03 will evaluate how plants(lettuce) grow in a newly developed system known as PONDS, or Passive Orbital Nutrient Delivery System. The PONDS are designed to bypass the lack of gravity in order to distribute water.(water on Earth is pulled downward, but in space this is not the case) The PONDS are able to increase the plant’s oxygen exchange and provide sufficient room for root growth.
- Adidas Boost in Space investigates the flow of nonuniform foam particles. It will look at mixing and packing behavior in the absence of gravity. Results will inform manufacturing process of Adidas Boost shoe soles, which contain polymer particles fused together and may prove helpful in optimization.
- Capillary-Driven Microfluidics in Space include capillary filling of microstructures, particle focusing and plasma separation, and microfluidic flow in thermal gradients.
- Spherical Cool Diffusion Flames Burning Gaseous Fuels will increase fundamental understanding of the physics of cool diffusion flames by observing quasi-steady spherical flames on porous burners in microgravity since cool flames had never been observed as steady spherical flames. Prior studies used drop towers, but drop tower experiments had uneven burn rates.
- Droplet Formation Studies in Microgravity evaluates water droplet formation, water flow, and pressure of Delta Faucet’s current H2Okinetic. H2Okinetic technology allows better control of droplet size and increases the speed of the drops, which creates a feeling of increased pressure for the end user as compared to jet systems available.
SpaceX has a number of resupply missions planned in the coming years for NASA and the International Space Station.
Future Crew Resupply missions for SpaceX Dragon 2 include a minimum of six flights
SpaceX CRS-21: 20 October 2020 (planned)
SpaceX CRS-22: scheduled
SpaceX CRS-23: scheduled
SpaceX CRS-24: scheduled
SpaceX CRS-25: scheduled
SpaceX CRS-26: scheduled
Prior to the next CRS mission, The SpaceX Crew Dragon spacecraft for Demo-2 will launch to the Space Station. The Cargo Dragon is a variant on the Crew Dragon. The Crew Dragon Spacecraft has already arrived at the launch site on Feb. 13, 2020 and is beginning final testing and prelaunch processing in a SpaceX facility on nearby Cape Canaveral Air Force Station for a crewed spaceflight.
The SpaceX Crew Dragon spacecraft is now planned to launch from American soil with crew which will mark the first time since the retirement of the Space Shuttle. NASA and SpaceX are preparing for the company’s first flight test with actual astronauts to the International Space Station as part of the agency’s Commercial Crew Program and as a follow up to the Demo-1 flight done in 2019 without a crew.
The SpaceX Crew Dragon will launch atop a Falcon 9 rocket and will send NASA astronauts Bob Behnken and Doug Hurley into space. The Crew Dragon will launch from historic Launch Complex 39A from NASA’s Kennedy Space Center in Florida.
